shrug-l: FL data for Address Geocoding

Counties often have good address databases, if you can get a copy (sometimes,
the county won't release the data).  For example, Brevard County's 911
address database is excellent and is available as a shapefile (points) from
their website.  Don't need to geocode it, just drop it on your map!

Although the parcel database is often the "best available" database for
geocoding, it is often not the best overall. Parcels usually have two
addresses - the owner address and the parcel address. Of these, the owner
address is almost always the most correct. The reason for this is that parcel
addresses are superfluous as the parcel number serves as the location ID for
the property appraiser. The owner address is the one that is usually best
maintained as that is the address to which the tax bills are sent. 
 
The best county data (if available) is an address point database created by
the county addressing staff in which there is only one address (the property
address). Not all counties have them. You can download Seminole County's
address points (known as Situs) from our web site,
http://www.seminolecountyfl.gov/pd/commres/gis/layerbib2.asp .  If you are
going with a professional system I would recommend Centrus.

I got a commercial geocoding package a couple years ago for $14.000 first
year and thereafter $4,000/yr for continuing update the addresses database
because that zip codes are updated by the USPS monthly (zip deletion,
splitting, merging, ...), new addresses are added all the time, counties are
split or merged, etc..  Generally speaking, I am happy about it.  However,
after a couple years in geocoding tens, if not hundreds, of millions of
addresses each year, I sometimes found that addresses can be misplaced miles
away or out of State including some in Florida using the current geocoder.
This happened even after the addresses were checked and then corrected if
necessary, against the latest NCOA (national change of address).

 

Interestingly, those "problematic addresses" were all put right on the money
through Google Map.  So I am currently evaluating Navteq which is said to be
the backbone for Google map address searches.  

 

Geocoding software venders normally each have their own "proprietary
criterion" of addresses matching and some might have implemented what they
called "aggressive intelligence" to give an output for addresses that do not
have an exact match.  This can be problematic because it gives you a wrong
location for those addresses rather than simply not geocoding it!!!.  

 

If your area is generally a County, I would suggest getting an address
database from a local source (Police, Sheriff, County property appraise, or
the local private vender).  If your project or application deals with
emergency or dispatching issues, you might need to consider some other
factors because one misplacement of an address can result in life/death.

 

Good luck.

I believe that it is Navteq for streets, Group 1 (Pitney-Bowes) for parcel
centriod and building footprint.  I will check with the Virtual
Earth/MapPoint Team and report back.  It may be stated in their EULA.

Do you know what source is for the Microsoft GIS data? I took a look at their
site and can't find the GIS metadata info that I would normally expect to
find.

Hello everyone: 
I am looking for the most updated FL data for address geocoding (regardless
of the price). I would appreciate greatly if you could share your knowledge
about and/or experience with the existing, most-up-to-date (i.e. best :-))
geocoding data available for Florida. 
Thanks in advance,
